INTERNAL-COMBUSTION ENGINE.

Application filed July 26, 1924. Serial No. 728,459.

This invention relates to internal combustion engines.

In internal combustion engines as heretofore constructed, the total amount of charge that can be drawn into a. cylinder is determined by the Volume of the cylinder. There is, therefore, an inherent limitation of the output of any given engine. Further than this low grades of'fuel cannot be successfully employed with the usual types of engines.

This invention is designed to overcome the above noted defects, and objects of such invention are to provide an internal combustion engine in which agreater charge can be forced into the cylinders than has been heretofore possible, in which a cheap grade of fuel may be employed, and in which an increased output may be secured.

An embodiment of the invention is shown in the accompanying drawings, in which 2 which are operatively connected with the an auxiliary driven shaft 9, such shaft/be ing operatively coupled by means of gearings such as shown at 10 with the engine shaft.

It is to be noted that the auxiliary cylinders 5 are spaced upwardly from the main working cylinders 1, and a storage compartment or chamber 11 is provided intermediate each pair of auxiliary and working cylinders. This storage reservoir communicates both with the main cylinder and'with the auxiliary cylinder by means of ducts 12 and 13 respectively.- Rotary valves 14 and 15 control these ducts and open and close them in a periodic manner hereinafter described. The auxiliary cylinders also are provided with ducts 16 which communicate with fuel inlet passages 17, the communication being controlled by valves 18, as may be seen from Figure 2.

The valves 14, 15 and 18 are of the rotary type, as may be seen from Figures 1, 2 and 3. They are preferably elongated cylindrical members provided with channels 19 cut through appropriate sides, as shown in Figure 3, and adapted to furnish passa e ways communicating with the respective nets in a well known manner. These rotary valves are also provided with hollow portions 20 into which a plurality of small holes 21 open. It is to be noted from reference to Figure 3 that these hollow portions are arranged adjacent recesses 22 formed in the cylinder block. It is intended that the rotary valves shall be oiled through this medium, that is to say, oil may be furnished by means of the cavities 22 and will pass through the apertures 21 into the enlarged hollow portion 20 of the rotary valve, thus facilitating their adequate oiling.

These rotary valves are each provided with gears operatively connecting them with the driven crank shaft 9, as shown in Figures 3 and 4. A gear 23 and a similar gear 24 are provided for the valves 15 and 18 and are connected by means of an idler 25 with a gear 26 carried by the auxiliary crank shaft 9. These gears are all of the same size and the gearing through which the crank shaft 9 is connected with the engine shaft is such as to drive the auxiliary crank shaft at the same speed as the engine shaft thus in turn driving the valves 15 and 18 at the same speed as the engine shaft. The valve 14 is provided with a, car 27 which meshes with a pinion 28 rigidly associated with one of the gears 23 or .24, as shown in Figure 4;. The ratio of the pinion 28 and the gear 27 is such that the valve 14 is driven at one quarter engine speed.

The operation of the apparatus is as follows:Assuming that one of the main pistons 2 is making a working stroke, the corresponding auxiliary piston 6 is then rising,

the valve 18 and communicating with the storage chamber 11 being established by the valve 15. This charge is forced into the storage com artment 11 under ressure and the intake 0 the main cylinder egins. The auxiliary cylinder is also drawing in a fresh charge of mixture while the main piston is descending. Thereafter, the mainpiston starts upward and compressing its normal charge. An instant after the passage at dead center, the valve 14 opens and the compressed charge stored in the compartment 11 is forced into the main cylinder. Also the auxiliary piston is descending and forces an additional supply of mixture throu h the chamber 11 and into the main cylin er. The valve 14 closes and the main piston completes its compression. The main cylinder charge is then exploded and the same cycle of operations is repeated.

It will be seen therefore, that means have been provided for augmenting the regular or normal charge drawn into a working cylinder, and that by this means an addi tional or auxiliary charge is forced into the It wi 1 be seen, therefore, that any amoun of charge may be forced into the main cylinder and that the output of the engine can be increased.

, conditions to Suppl ing the supply of air in themain cylinder. This procedure will be found hi hly desirable when a very low grade 0% fuel is being used. 7

It will be seen, therefore, that an internal combustion engine has been provided which has an output considerably in excess of that supplied by a similar engine under normal conditions, which ma be operated to secure an desired supply 0 mixture for the main cy inder and any desired compression. Obviously the proportioning of the stroke and bore of the main and auxiliary cylinder will be covered by the amountof compression desired and the amount of volumetric displacement.

Although the invention has been I described in considerable detail, it is-to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

An internal combustion engine comprising a main cylinder, an auxiliary cylinder,

and a storage compartment between said cylinders, a main piston within said main cylinder, an auxiliary piston Within said auxiliary cylinder, means for reciprocating said auxiliary piston a plurality of times for each stroke of said main piston, a rotary inlet valve controlling the admission of charge to said auxiliary cylinder, a rotary valve controlling discharge of the compressed charge from said auxiliary cylinder to said storage compartment, and a rotary discharge valve controlling discharge of the compressed charge from the storage compartment to said main cylinder, said last mentioned valve operating at a lower speed of rotation than said first mentioned valves.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee,

in the county of Milwaukee and State of Wisconsin.
